Two of my best earners have been a Russian .net and a Farsi .net. The .com will always be more valuable, but the .net should be fine in the long run.

Might also be due to indexing, Google and Yahoo does not differentiate between .com and .net, both are converted into punycode once indexed. And once converted to punycode by the search engine 100% of users can access your idn, regardless of whether they installed IE7.
